Yeah, and then there are many enterprises that still use XP (edge case, but it may be well hundreds of thousands worldwide still) or Win 7 (possible millions of companies). It is not all smooth sailing in enterprise level either, many companies are upgrade averse, and if the stuff works, then why upgrade it.
From business standpoint, it simply bleeds you potential profits. If tens of percents skimp on two of your OS iterations in a row and keep windows 10 (which most of were “free” upgrades from Win 7 to begin with) then you are losing lot of revenue in a long run. I got the original win 10 upgrade in 2015 (bought win 7 in 2011) , in 2020 build a new PC and still use that licence on it.I possibly see myself using Win 10 well into 2026/2027 when my PC is due for complete replacement. So that is over 15 years period where MS saw no money from me while I still use completely legal version of OS. If there was no TPM requirement, I would probabably already be on Win 11
You could say this meme hits really hard
If I was not using my PC for gaming also, I would probably say fuck them and be on Linux too. But gaming on Linux is cancer.
